Grafana Agent Configure Grafana Agent integrations_config cadvisor_config
cadvisor_config block configures the
which is an embedded version of
cadvisor. This allows for the collection of container utilization metrics.
The cAdvisor integration requires some broad privileged permissions to the host. Without these permissions the metrics will not be accessible. This means that the agent must also have those elevated permissions.
A good example of the required file, and system permissions can be found in the docker run command published in the cAdvisor docs.
